Tara Parker-Pope wrote for The New York Times on June 3, 2008:
“(…) Some doctors say the real concern is not older cellphone users, who began using phones as adults, but children who are beginning to use phones today and face a lifetime of exposure.
(…) According to the Food and Drug Administration, three large epidemiology studies since 2000 have shown no harmful effects.
(…) The F.D.A. notes, however, that the average period of phone use in the
studies it cites was about three years, so the research doesn’t answer
questions about long-term exposures. (…)”
